Similarly to the work done earlier with writes, this series
converts signal32 to using user_read_access_begin/end and
unsafe_get_user() and friends.
Applies on to of the signal64 series, ie on merge-test (ca6e327fefb2)
Christophe Leroy (10):
signal: Add unsafe_get_compat_sigset()
powerpc/uaccess: Also perform 64 bits copies in
unsafe_copy_from_user() on ppc32
powerpc/signal: Add unsafe_copy_ck{fpr/vsx}_from_user
powerpc/signal32: Rename save_user_regs_unsafe() and
save_general_regs_unsafe()
powerpc/signal32: Remove ifdefery in middle of if/else in sigreturn()
powerpc/signal32: Perform access_ok() inside restore_user_regs()
powerpc/signal32: Reorder user reads in restore_tm_user_regs()
powerpc/signal32: Convert restore_[tm]_user_regs() to user access
block
powerpc/signal32: Convert do_setcontext[_tm]() to user access block
powerpc/signal32: Simplify logging in sigreturn()
